Application November 29, 1951, Serial No. 258,900

This invention relates to sights for use in connection withl the aimingof arrows when shot from a bow either in target shooting or in hunting;and has for its object to provide means of a nature particularly adaptedto facilitate the setting of a sighting point to meer, the peculiarrequirements of any particular marksman to suit his own manner ofshooting and the type of bow or arrows' which he is in the habit ofusing.

' The general and variousV methods of sighting involving, for instance',point of aim and point of loose, are well known to those familiar withthis art and will not be discussed at length hereinit being thoughtsuflicient to mention that any mechanical sight should be capable ofbeing set or coordinated not only with the actual target distances butwith the aiming habits of the archer.

Furthermore, as the limbs of the bow are movable by flexion relative tothe handle, it is highly desirable that any sight be free of anyinfluence by such movement of the proximate bow limb, so that it is animportant object of the present invention to provide a sight which ismounted solely upon the rigid handle and is free of disturbing influenceof any flexible part ofthe bow.

A further yobject of the invention is to provide a sighting point orbutton which is adjustable to and between upper and lower positionsabout a single fixed location point, which location point, in turn, isrigidly maintained in a iixed position relative to the handle of the bowand independently 'of either limb of the bow.

Still further, the said invention is characterized by the provision of asight arm, swingable vertically and forwardly of the bow on a pivotwhich isfflxedly carried by the handle of the bow and which is free ofany infiuence by the exing movement of the limbs of the said bow.

f The invention still further contemplates the provision of a flat platefirmly secured at its lower end portion to the rigid handle of the bowand freely spaced from the upper flexible limb of the bow, said platelying in a true plane extending through both the bow and the bow string,a sight arm being pivoted on said plate and swingable in a verticalplane over the face of the plate whereby calibrations determined bytrial by the archer may be marked on the plate for future reference, alaterally adjustable sighting point or button being carried by the outerend portion of said arm.

Still further objects or advantages additional or subsidiary to theaforesaid objects, or resulting from the construction or operation ofthe invention as it may be carried into effect, will be- 3 Claims. (Cl.33-46) 2 come apparent as the said invention is' hereinafter furtherdisclosed.

In carrying the said invention inte e'ect, I may adopt the novelconstruction and arrangement of parts hereinafter described, by way ofexample, having reference to the accompanying drawing, wherein:

Figure l is a side elevation of part of an archery bow showing theadjustable sight of the present invention attached thereto; and

Figure 2 is a top plan view of the said sight, with the plate thereofshown in cross section taken on a planeindicated by the line 2 2A inFigure l.

Similar characters of reference indicate similar parts in both figures`of the drawing.

The handle element I 0 of the bow is shown as being equipped with theusual arrow rest I I, and the said handle has extending from its upperend the iiexible limb I2 as in a steel bow. In an allwood bow the limbsmay be integral with the handle, but it is intended that the feature ofmounting ythe sight so that it is free of any flexible portion or limbof the bow is intended to be maintained regardless of the particulartype of bow to which the sight may be applied. I3 is a flat plate, orsemi-circular form in outline, provided with a stud or pivot I4 at thecenter offits curved outline and further provided at its lowerend withlaterally extending lugs I5 for attachment to the upper end portion ofthe handle I0, as by means of screws I6, although the actual manner ofattachment is one of choice or convenience as will be well understood.

Care should, however, be exercised in attaching the plate to the handlein order to ensure that the said plate will lie in a true planeextending through both the bow and the bow string (not shown) in orderthat a sight arm I1, which is swingably mounted on the said pivot I4,may be adjusted truly in the same plane in which the bow is drawn inshooting. Where the type of mounting shown is used, the face of theupper end of the handle Imay be squarely recessed to provide a atsurface at I8 and a locating shoulder I 9 to determine the correctpositioning of the said plate I3 on the bow.

The plate I3 has formed therein an arcuate slot 20 through which a stud2| carried by the arm II and provided with a lock nut 22 extends; andthe said arm is further provided with an indicatr 23 to ride thesemi-circular periphery of the p a e.

Toward the outer end of the said arm I1 are shown as an example, twoholes 24 and 25 in 3 either of which may be secured a cross pin 2B.which pin is threaded for adjustment as to the extent which the point orbutton 21 may DI'OJ'eCi? laterally of the general plane of the sight.The purposes of this adjustment to meet lateral variations of arrowflight due to wind, type of arrow being used or other factors will bereadily recognized by those familiar with archery and therefore, willnot be discussed in detail herein.

It will 'be seen the arm ali @i this sieht may be of any convenientlength, and that-*the actual lineal sweep of the adjustment at thearcuate slot 20 is greatly multiplied at the pin 2,6, due to theAdifference of radius. in radii may be varied, if desired, by simplymoving the said pin to a hole closer t@ or .fuimer from the pivot I4.

This diligence By whatever mechanical means 'the lvariation of theradius of the arc of movement ofgfthe pin 26 is accomplished, itperjmits the user to not only vary the Osier-.eil range cf @desiring.eisiitiiia to increase or decrease the agitent of .actua adiustmeritrequired ,per .0f .,ual'dage: and .this variati-dn fir-bril .finer to.waneer i adi-deinem will diner-ent archerslhe Y.fici/.ice described.may .be --Qf Mery rdbuei construction without lossof'easeangl,sin-@.Ohe in the ,Swinging adjustment of siehtlarni H, .andthe sight AIJ may .bevreadilv andiirmly locked in positions ,oi,edJiSimeni Witheet diriger i df disturbing theadiiiimenb .in-.deine 5o.
